Appellate Affirmance for Unchallenged Alternative Dismissal Grounds and Preclusive Amount-in-Controversy Findings in Diversity Cases

Precedents Cited

Standards of Review and Appellate Disposition

• Gupta v. McGahey, 709 F.3d 1062 (11th Cir. 2013): cited for de novo review of subject matter jurisdiction determinations, framing the appellate lens for the jurisdictional ruling.
• Peer v. Lewis, 606 F.3d 1306 (11th Cir. 2010): cited for abuse-of-discretion review of sanctions decisions; the court uses this to uphold the district court’s refusal to sanction Walmart.
• Jenkins v. Anton, 922 F.3d 1257 (11th Cir. 2019): cited for abuse-of-discretion review of recusal decisions.
• Silva v. Pro Transp. Inc., 898 F.3d 1335 (11th Cir. 2018): provides the definition of “abuse of discretion” and is also used to anchor the district court’s inherent power to sanction bad-faith conduct.
• Sapuppo v. Allstate Floridian Ins. Co., 739 F.3d 678 (11th Cir. 2014): the pivotal appellate doctrine in the case—when a district court relies on “two or more independent, alternative grounds,” an appellant must challenge all grounds; failure to do so constitutes abandonment and warrants affirmance.
• Kernel Records Oy v. Mosley, 694 F.3d 1294 (11th Cir. 2012): cited for the principle that the appellate court may affirm “on any ground supported by the record,” reinforcing the panel’s ability to affirm based on the unchallenged Rule 11 ground alone.

Subject Matter Jurisdiction, Diversity, and Amount in Controversy

• Kokkonen v. Guardian Life Ins. Co. of Am., 511 U.S. 375 (1994): cited for foundational limits of federal jurisdiction and the presumption against it; supports placing the burden on Nichols as the party asserting jurisdiction.
• Morrison v. Allstate Indem. Co., 228 F.3d 1255 (11th Cir. 2000): cited for two propositions: subject matter jurisdiction cannot be conferred by consent; and courts need not accept damages claims at face value when scrutinizing amount in controversy.
• Federated Mut. Ins. Co. v. McKinnon Motors, LLC, 329 F.3d 805 (11th Cir. 2003): cited for the “good faith” standard—plaintiff satisfies amount in controversy by claiming a sufficient sum in good faith, though courts may test that claim.
• McIntosh v. Royal Caribbean Cruises, Ltd., 5 F.4th 1309 (11th Cir. 2021): cited for the court’s duty to verify jurisdiction sua sponte and the requirement to provide notice and an opportunity to be heard before deciding jurisdictional issues on its own motion. The magistrate judge’s show-cause hearing is treated as satisfying this procedural safeguard.

Issue Preclusion (Collateral Estoppel) and Changed Circumstances

• CSX Transp., Inc. v. Bhd. of Maint. of Way Emps., 327 F.3d 1309 (11th Cir. 2003): supplies the four-part test for issue preclusion, which the court applies to bar Nichols from relitigating the amount-in-controversy determination.
• Napper v. Anderson, Henley, Shields, Bradford & Pritchard, 500 F.2d 634 (5th Cir. 1974): provides the “changed circumstances” escape valve—once issue preclusion applies, relitigation is permitted only upon proof of a change in relevant circumstances. The panel notes Nichols failed to show meaningful change.
• Bonner v. City of Prichard, 661 F.2d 1206 (11th Cir. 1981) (en banc): cited to explain why pre-October 1, 1981 Fifth Circuit decisions (including Napper) remain binding in the Eleventh Circuit.

Sanctions, “Ex Parte” Communications, and Local-Rule Compliance

• Silva v. Pro Transp. Inc., 898 F.3d 1335 (11th Cir. 2018): invoked again to recognize inherent authority to sanction bad faith; the court ultimately finds no bad-faith rule violation by Walmart warranting sanctions.
• Black's Law Dictionary (12th ed. 2024): used to define “ex parte” and support the conclusion that copying Nichols on an email to the court defeats the “without notice” element.

Recusal Standards

• Christo v. Padgett, 223 F.3d 1324 (11th Cir. 2000): states that to warrant recusal under § 144, facts must convince a reasonable person that bias actually exists; supports rejecting Nichols’s conclusory claims.
• Hamm v. Members of Bd. Of Regents of State of Fla., 708 F.2d 647 (11th Cir. 1983): emphasizes the “extrajudicial source” doctrine and that adverse rulings, comments on lack of evidence, and courtroom friction are typically insufficient for recusal absent pervasive bias—directly answering Nichols’s complaints about the magistrate judge’s conduct and rulings.

Magistrate Judge Authority to Issue an R&R Without Party Consent

• PB Legacy, Inc. v. Am. Mariculture, Inc., 104 F.4th 1258 (11th Cir. 2024): cited for the proposition that magistrate judges may perform “ministerial tasks,” including issuing R&Rs subject to de novo review, without the parties’ consent.
• Kernel Records Oy v. Mosley, 694 F.3d 1294 (11th Cir. 2012): referenced again in this context to reinforce affirmance on any record-supported ground and, in practice, the adequacy of the review structure.

Rules Referenced as Operative Legal Framework

• Fed. R. Civ. P. 12(h)(3): mandatory dismissal once lack of subject matter jurisdiction is found.
• 28 U.S.C. § 1332: diversity jurisdiction requirements, including the $75,000 threshold.
• 28 U.S.C. § 455(a) and 28 U.S.C. § 144: recusal standards.
• 28 U.S.C. § 636(b): magistrate judge authority over pretrial matters and R&Rs.
• 11th Cir. R. 26.1-2: certificate of interested persons must include trial judges; used to reject the claimed “conflict.”
• The opinion cites “Local Rules 83.4 and 83.6(a)” and “Local Rule 7.5” as the procedural baseline for attorney appearance and motion-response timing; the court uses these to conclude Walmart’s conduct was compliant and non-sanctionable.

Legal Reasoning

1) Dispositive Appellate Doctrine: Failure to Challenge an Independent Alternative Ground

The panel’s primary appellate move is procedural rather than merits-based: it treats the district court’s dismissal as resting on two independent grounds—(i) lack of subject matter jurisdiction and (ii) Rule 11 dismissal as a non-monetary sanction. Under Sapuppo v. Allstate Floridian Ins. Co., Nichols had to challenge both. Because she only attacked the jurisdictional rationale, she abandoned any challenge to the Rule 11 basis, requiring affirmance on that ground alone.

This use of abandonment doctrine functions as a screening rule: appellate courts will not expend resources reviewing one ground when another unchallenged ground independently sustains the judgment.

2) Jurisdictional Merits as Reinforcement: Issue Preclusion and Insufficient Good-Faith Amount in Controversy

Although the panel could stop at abandonment, it also explains why jurisdiction failed. The court treats the prior dismissal’s amount-in-controversy determination as an issue that can be precluded if the CSX Transp., Inc. v. Bhd. of Maint. of Way Emps. elements are satisfied. It then points to Nichols’s failure to identify changed circumstances as required by Napper v. Anderson, Henley, Shields, Bradford & Pritchard.

The opinion underscores that merely pleading “damages exceeding $75,000” does not end the inquiry. Under Morrison v. Allstate Indem. Co. and Federated Mut. Ins. Co. v. McKinnon Motors, LLC, courts credit good-faith claims but may test them when the record shows the figure is unsupported. The magistrate judge conducted a show-cause hearing consistent with McIntosh v. Royal Caribbean Cruises, Ltd., and Nichols’s own statements (medical expenses about $4,500; no asserted work-limiting vision change; no evidence of lost wages or further treatment) undercut the plausibility of exceeding $75,000.

3) Sanctions Against Walmart: No Rule Violation, No “Ex Parte” Contact

The court rejects Nichols’s request to sanction Walmart because the alleged misconduct did not violate cited procedural/ethical rules. It reasons that: (i) counsel appearances complied with the referenced local rules; (ii) the response to a motion to compel was timely under “Local Rule 7.5”; and (iii) an email to the court seeking an extension was not “ex parte” because Nichols was copied—consistent with the definition of “ex parte” drawn from Black's Law Dictionary (12th ed. 2024).

4) Recusal: No Extrajudicial Bias, and Required Disclosures Are Not Conflicts

Applying 28 U.S.C. § 455(a) and 28 U.S.C. § 144, the court finds no reasonable basis to question impartiality. It uses Christo v. Padgett and Hamm v. Members of Bd. Of Regents of State of Fla. to emphasize that adverse rulings, comments about evidentiary shortcomings, and courtroom friction generally do not establish pervasive bias, especially absent an extrajudicial source.

The claim that the magistrate judge’s name on the certificate of interested persons created a conflict failed because 11th Cir. R. 26.1-2 requires inclusion of trial judges; compliance with a disclosure rule cannot itself create disqualifying interest.

5) Magistrate Judge Authority: R&R Without Consent Is Permitted

The panel rejects the argument that Nichols’s consent was required for the R&R. Under 28 U.S.C. § 636(b) and PB Legacy, Inc. v. Am. Mariculture, Inc., magistrate judges may conduct hearings and issue R&Rs on dispositive matters as delegated, subject to district judge review, without party consent. The consent requirement generally attaches to full civil consent jurisdiction under § 636(c), not to § 636(b) R&R practice.

6) Recordkeeping: No Prejudicial Error Shown

The court briefly addresses and rejects claims of inaccurate docketing/labels, noting the docket reflected correct information and that any typographical issues did not affect the outcome.

Impact

• Appellate practice consequence: The opinion reinforces that in the Eleventh Circuit, an appellant’s failure to challenge every independent ground for dismissal is often fatal. Even potentially arguable jurisdictional issues will not matter if an alternative dismissal ground stands unchallenged.
• Diversity jurisdiction gatekeeping: The decision illustrates robust judicial policing of the amount-in-controversy requirement—especially where a plaintiff previously litigated and lost on that specific issue. Litigants should expect show-cause proceedings and evidentiary probing where claimed damages appear inflated or speculative.
• Preclusion in jurisdictional contexts: While subject matter jurisdiction itself cannot be created by consent, factual/legal determinations underlying jurisdiction (here, amount in controversy) may be treated as precludable issues when the CSX criteria are met, limiting repeat filings that attempt to repackage the same damages theory.
• Magistrate judge procedure clarity: The opinion provides a clean rejection of a common pro se misconception: issuing an R&R is not an exercise of unauthorized “final” power and does not require party consent.
• Sanctions and “ex parte” allegations: The panel’s reliance on a standard definition of “ex parte” and straightforward local-rule compliance analysis signals that sanctions motions premised on misunderstandings of routine scheduling communications are unlikely to succeed.

Practical note: Although labeled “NOT FOR PUBLICATION,” the reasoning is still informative for litigants and courts as persuasive guidance, particularly on procedural defaults (abandonment) and on how district courts may structure jurisdictional inquiries and sanctions analyses.
